T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file was detected as malicious by a ML classifier and ClamAV, indicating a high likelihood of malicious intent. The document body, though heavily obfuscated, contains text related to a 'silent auction winner thank you letter', suggesting a social engineering lure. The embedded URL 'https://golowaki.ru/wix?keyword=silent+auction+winner+thank+you+letter' likely serves as the primary payload delivery mechanism or a redirection point for further malicious activity.

External URI info PDF_URIPDF contains an external URL action
-
Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTALThe same indirect object (N G) is defined more than once with different body bytes. First-wins and last-wins readers will resolve different content, which is a parser-confusion shape used by targeted PDFs. Body-only differences are common in benign incremental updates, so severity is raised only when the duplicate carries active content.

Embedded URL info EMBEDDED_URLOne or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.URL https://golowaki.ru/wix?keyword=silent+auction+winner+thank+you+letter
